Problems solved by technology

[0002] The omnidirectional requirements for antennas in the use of unmanned aerial vehicles or other image transmission equipment are getting higher and higher. In addition, there are more and more communication links, and dual-frequency antennas can no longer meet the existing communication needs.
Moreover, in order to ensure the quality of signal transmission, the antennas of unmanned aerial vehicles are often designed with large volumes.
However, for the field of unmanned aerial vehicles, the large size of the antenna often affects the design of unmanned aerial vehicles, which is not conducive to the miniaturization design of unmanned aerial vehicles.

Abstract

The invention provides an unmanned aerial vehicle and an antenna thereof. The antenna comprises a first antenna module and a second antenna module, the first antenna module and the second antenna module are oppositely arranged, and each of the first antenna module and the second antenna module comprises a feed band and an oscillator unit. Each oscillator unit comprises a first frequency band branch knot, a second frequency band branch knot and a third frequency band branch knot, wherein the first frequency band branch knot and the third frequency band branch knot are located on the two sides of the second frequency band branch knot respectively, the length of the first frequency band branch knot is larger than that of the second frequency band branch knot, the length of the second frequency band branch knot is larger than that of the third frequency band branch knot, and the first frequency band branch knot comprises a body and a bent part arranged at the tail end of the body. The antenna is small in size, and it is ensured that the antenna can adapt to miniaturization development of unmanned aerial vehicles.

Description

technical field [0001] The invention relates to the technical field of drone antennas, in particular to an unmanned aerial vehicle and its antenna. Background technique [0002] The omnidirectional requirements for antennas in the use of unmanned aerial vehicles or other image transmission equipment are getting higher and higher. In addition, there are more and more communication links, and dual-frequency antennas can no longer meet the existing communication needs. Moreover, in order to ensure the quality of signal transmission, the antennas of unmanned aerial vehicles are often designed with large volumes. However, for the field of unmanned aerial vehicles, the large size of the antenna often affects the design of unmanned aerial vehicles, which is not conducive to the miniaturization design of unmanned aerial vehicles. Contents of the invention [0003] The object of the present invention is to provide a smaller unmanned aerial vehicle and its antenna. [0004] An ant...
